A few tranny issues
You don't have a clue unless you check it.
Sometimes you have to help yourself since few , if any , will come to your house and look at it for you.
However I do greatly appreciate the help all give here and think this forum is truly awesome.
And yes I offered a little sarcasm intended in good humor so I hope you weren't offended.
you said you haven't checked your fluid yet, but it appeared ok (your words not mine). That's ludicrous. Unless it was a typo or something.
Then when I asked you, it seemed you gave me some sarcasm. Because we all know Google and YouTube can't check your trans fluid.
So what's the mix up?

P0731 - Gear ratio on first gear
And he says it won't hold pressure on the forward drum.
He says the forward drum is probably cracked, and the tranny needs a rebuild.
He wants $2,600 to do a complete rebuild of the tranny.
He claims they charge more than if we bought a rebuilt tranny online & had it installed, because he rebuilds them to a higher standard.
Specifically he says his tranny rebuilds include the following upgrades that you don't typically get with a rebuilt-tranny bought online or at a parts supplier:
1.) Heavy Duty Clutches (to help it last longer)
2.) High-pressure Boost Valves (for improved performance)
Being a novice here, I'm asking you guys. Are these legit upgrades, or is he pulling my leg? I looked online and saw various "high pressure boost valves" selling for ~$35. IDK how many of those are needed. But is this the same part that he is saying most stock rebuilt trannys use a lower quality of?
What about heavy-duty clutches? Are those a real thing, or just something he's making up? Most trannys don't have heavy-duty clutches?
He says they use the strongest / highest-quality parts to enable it to last as long as possible.
Thanks for your help guys!!

Yea, if a Good tranny shop is going to do a "re-built" most do an over the top job, with the heavy duty parts, they build it with the parts used in like an Ambulance package. All heavy duty.
Off the shelf "re-man's" are just that, just the basic re-built parts, on an assembly line, type set-up.
The question is........what do you want?? Keeping this van forever?
Get it up and running and flipping it??
I broke down in South Carolina in '05, 800+ miles from home, blew my E4OD all over the highway, ended up at a local shop, he worked on it until 11pm, next morning got it done and installed by noon, and I was on my way again.........he re-built it with all heavy duty ambulance package parts, I would have to up shift the tranny with the gas pedal, other wise it would wine out before it shifted.........drove that thing for another 10 years and 150+K and even swapped it out in my '92 for about 6 months, until the front seal let go and called it done......point is, the local guy charge me $2200, big bite, but divide that over the years and mileage.......I got a good deal with it.
The one I'm running in the '92 now is over the counter from a local re-builder/tranny shop, I paid $1450 for that one, 2 years ago, took 2 days to swap it out, 20 quarts of fluid, and it didn't shift out of 1st gear, had to take it back to them to rebuild the valve body, but I don't think I'll get 10 years, and I don't drive the '92 cube van that much anymore.......I'll get by with it.
So.....you asking about an 5R110W tranny?? over the counter, low end, $1,750 high end $2,400 with a $1,000 core charge. And this shop want $2,600 complete?? Including the 18 quarts of fluid at $7.50 per quart......hmm.......your choice.
Maybe Mark will chime in too...
Wildman makes some good points to think about...
I have no clue, but I wonder if there are any TSB’ on your transmission or software upgrades that might solve the problem? My sons PT cruiser was having simular problems and a shop flashed the computer and it fixed his problem..
I guess you have been reading on the code..

His description of upgraded parts is legitimate. I included heavier duty clutches, too, but I only did the pressure uprades if the customer asked for it.
Mark do you think it is worth pushing back at the possibility of a misdiagnosis based on the info in this link?

We are ready to pay the $2,600, but of course wouldn't want to in case they are going the "easy" "catchall" route of a rebuild, when in fact the root cause may be simpler and cost less...
Thoughts?
Annaleigh the shop has a pretty good reputation. They've been in existence for like 60 years. They do all the tranny work for our city municipality fleet & various other fleets. Although today I called a competitor and he didn't think they were that great, but I take a competitors opinion with a pretty large grain of salt.
They give a 1 yr 12,000 mile warranty.
I am not a transmission person and am somewhat intimidated by automatic transmissions though I will do some minor work on them.. I have been watching the threads about transmissions because though my AOD is working fine at the moment, I am not sure of the mileage or condition. I want to learn the best rout when I do have a problem one day..
Bad Bad trip when you find yourself miles away from home on vacation and it goes out!!
Ive seen lots of people on this forum with trans issues that turn out to be "a" problem, instead of a rebuild. I hate automatic transmissions. And computer chips. Both are magical boxes of voodoo. They defy all mechanical logic.
I truly wish you luck with your problem. Stick with Mark Kovalski here- he will help.
As far as heavy duty parts: I am a huge fan of good parts and of parts upgrades. But my van has at least 193,000 miles on its transmission, and I fully suspect the other 113,000 miles (before me) were with the same unit. I'm not feeling the "upgrades" on this one.

you may have just jinxed yourself
So in three days and $2,700 later, we will have a brand-new high-performance, heavy-duty transmission, that will hopefully last us another 150,000 miles, if we take care of it.
and for the record, the local Ford dealership wanted almost $6000 to put in a remanufactured transmission that would not have the heavy duty or higher performing components.
So I feel happy, both with the outcome, and that I was able to do some due diligence checks, which is always comforting when you're going to drop a few thousand dollars for a purchase that you are fairly ignorant about.
Thanks all for your help. I greatly appreciate it!
